Chelsea, under manager Xabi Alonso, has become a thrilling yet defensively vulnerable Premier League side this season. They have scored 15 goals and conceded 13 in six matches, averaging 4.7 goals per game. Their attack, featuring Cole Palmer, João Pedro, and Morgan Rogers, significantly over-performs its expected goals. However, the team has not kept a Premier League clean sheet in 22 games, highlighting a major defensive weakness stemming from Alonso's high-risk, high-reward system, similar to his approach at Bayer Leverkusen. A 3-0 defeat to Brentford served as a wake-up call. Encouragingly, a 5-1 victory over Bournemouth showed signs of improvement, with Chelsea adopting a 4-4-2 shape out of possession. The return of Moisés Caicedo and the leadership of Jordan Henderson bolstered the midfield, providing better defensive balance. While risks remain, these adjustments offer hope for greater consistency and a push for European football.
